Abstract: PURPOSE: To provide non-conductivity and proper heat conductivity (the radiation of the heat transmitted to a substrate from a heater) in the substrate structure of an ink jet printer. CONSTITUTION: A drawing is a cross section and constituted of a plastic substrate 26, a metallization layer 30, a buffer (titanium) layer 36 and a dielectric layer 34. The heat conductivity of plastic is 1/5 that of glass and 1/400 that of silicon but, by using the metallization layer 30, this becomes a sink tank and heat conductivity necessary for heat radiation is obtained. Further, as plastic, one with a low max. practical temp. can be used. The insulation between individual heaters is obtained by the dielectric layer 34.
